Recently, 3-dimensional graphic technologies are topics of rapidly growing importance in the industrial fields such as those dealing with curved surfaces. When designing for a curved surface, methods for transformation of arbitrary regions on the curved surface into flattened forms are very important in manufacturing processes. The purpose of this paper is to describe a scheme for transformation of various regions on a curved surface subject to the following conditions. First, materials which constitute regions on a curved surface have different types of elasticity. Second, an objective curved surface has some regions whose shapes are fixed. Third, lengths of border lines between two regions need to be made equal to each other. As typical and practical applications, examples of shoe models corresponding to each case are presented to illustrate the method that transforms the various regions into flattened forms.
